Copper-catalyzed aerobic oxyarylation of [1,2,3]triazolo[1,5-a]pyridines is developed. Notably molecular oxygen was utilized as one of the reagents and the transformation resulted in the formation of novel pyridinium triazolinone ylides. A basic mechanism for the one-pot process is proposed and further functionalization of the ylidic products were also presented.

The triazole ring in 1,2,3-triazolo-pyridines and -quinolines, and in 1,2,3-triazoloisoquinolines can be opened with loss of nitrogen.The reagents described are bromine, aqueous sulphuric acid, glacial acetic acid, and selenium dioxide; the products from the triazolopyridines are dibromomethyl, hydroxymethyl, acetoxymethyl, and acyl derivatives of pyridine.The generality of the reactions is discussed.The first reported reaction in which the six-membered ring of a 1,2,3-triazolopyridine is opened, by hydride reduction, gives a triazolylbutadiene.
